Taking Back the Night -- International Dark Skies Week

Special Guests

There are millions of urbanites who have never seen the wonders of a truly dark night sky. Scott Kardel of the International Dark Sky Association is fighting to restore the sky our ancestors knew so well. Emily Lakdawalla takes us out to an asteroid named Lutetia, while Bill Nye asks for help to Save Our Science (SOS). Astronomer Bruce Betts will tell Mat Kaplan about some of the brighter objects in that night sky during What's Up!
